20090039009 | DISTRIBUTOR PLATES FOR COMPOSITE PRESSURE VESSEL ASSEMBLIES AND METHODS - The present invention provides: a distributor plate for a composite pressure vessel. The distributor plate includes a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening. Radial slits are formed in the disk to define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side around the central opening. The present invention also provides a water treatment vessel that includes one or more distributor plates, a method for manufacturing a composite pressure vessel that includes one or more of the distributor plates and a method for preparing a composite pressure vessel that includes one or more of the distributor plate for use as a water treatment apparatus. | 02-12-2009 |
20090166273 | FLOW-CONTROL SUPPORTS FOR DISTRIBUTOR PLATES IN COMPOSITE PRESSURE VESSEL ASSEMBLIES - The present invention provides a flow-control support for a distributor plate in a composite pressure vessel. The distributor plate includes a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening and a plurality of fluid flow passages through the disk. The flow-control support is disposed between the bottom side of the disk and an inner side of an end of a thermoplastic liner assembly. The flow-control support includes a spirally fluted upper surface that is adapted to direct fluid flowing from a supply pipe disposed in the central opening of a distributor plate that is supported by the flow control support such that the fluid swirls in a space between the bottom side of the distributor plate and an inner side of an end portion of a water treatment vessel. The swirling water insures that fluid is distributed to substantially all of the fluid flow passages through the disk during backwashing operations. | 07-02-2009 |
20100101658 | COMPOSITE PRESSURE VESSEL ASSEMBLY CONTAINING DISTRIBUTOR PLATE - The present invention provides a composite pressure vessel containing a distributor plate. The distributor plate comprises a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening. The disk is provided with a plurality of radial slits, which define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side such that it swirls around the central opening. The perimeter edge of the distributor plate is joined to an inner side of a thermoplastic liner during or immediately after the thermoplastic liner is formed by a blow-molding process or a rotational molding process. | 04-29-2010 |

Radial slits are formed in the disk to define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side around the central opening. | 10-21-2010 |
20110192781 | HOUSING FOR REVERSE OSMOSIS FILTER CARTRIDGE AND METHOD OF FORMING SAME - Housings for reverse osmosis filter cartridges and methods of making the same. The housings include: ( | 08-11-2011 |
20130062266 | WATER FILTRATION SYSTEM AND WATER FILTRATION SYSTEM HOUSING WITH CLOSING ASSEMBLY - A water filtration system utilizes a housing configured to utilize various types of filter media and having a press-sealed closing system. The closing system includes a head portion defining a head opening, a lock member, and a lid member. The lock member releasably engages the head portion such that an abutment section of the lock member projects into the head opening. The lid member is received by the head portion to cover the head opening, and has an outward-facing press section configured to abut an inward facing portion of the abutment section of the lock member when the lid member is covering the head opening. Pressure generated within the housing during water filtration presses the lid member in an outward direction and causes the lid member press section to press against the abutment section of the lock member to substantially prevent disengagement of the lock member from the head portion. | 03-14-2013 |

20090054856 | REDUCED-PRESSURE SYSTEM AND METHOD EMPLOYING A GASKET - A reduced-pressure treatment system for treating a tissue site on a patient includes a gasket releasably attached around a perimeter of the tissue site that may remain in place for an extended time and allows an over-drape to be attached to it. The system and method further may include a manifold sized and configured to be placed in contact with the tissue site; the over-drape positioned over the manifold and sealed to the gasket to create a sealed space between the over-drape and the tissue site; and a reduced-pressure source fluidly coupled to the sealed space to deliver reduced pressure to the tissue site. A method is also presented. | 02-26-2009 |
20100069829 | THERAPY DELIVERY SYSTEMS AND METHODS - Fluid removal systems and methods for removing fluid from a tissue site are presented. The system includes a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to a tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site on the patient. The treatment-fluid collector receives the treatment fluid and a recruited fluid from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls fluid from the interstitial and intracellular space. A reduced-pressure treatment subsystem may also be included, among other things, for removing ascites and other fluids from a body cavity. | 03-18-2010 |
20100069885 | SYSTEMS AND METHODS FOR CONTROLLING INFLAMMATORY RESPONSE - A method and system for controlling inflammatory response at an internal tissue site of a patient utilizes a reduced-pressure treatment device. Controlling the inflammatory response may be accomplished in a number of ways that involve treating the inflammatory milieu. Treating the inflammatory milieu may include removing or moderating pro-inflammatory stimuli, e.g., fluids, enhancing perfusion of the tissue at or near the internal tissue site, or providing reduced-pressure therapy. The reduced-pressure treatment device is placed at or near the internal tissue site and is fluidly coupled to an external reduced-pressure source. The reduced-pressure treatment device provides reduced pressure proximate the tissue site and treats the inflammatory milieu. The reduced-pressure treatment device for controlling inflammatory response may be a minimally-invasive treatment device. | 03-18-2010 |
